It's hard for a laptop to upgrade. The only wise thing you can do is buy some extra ram. You can also buy a Extern Video card, but I don't think it's really practical.
It is very unlikely that you can upgrade the video card in your laptop, only a few makes/models do. All you can really upgrade is the RAM hard drive, and CPU.
